643134-9

Headers, Male Pins Overview

The TE Connectivity AMP Connectors part number 643134-9 is a 16-position vertical header assembly belonging to the MTA-156 series. Designed for through-hole PCB mounting, this connector features a 3.96 mm (0.156 inch) pitch and utilizes tin-plated contacts. It is configured as a straight header with a natural-colored polyamide (PA) housing. The component is rated for 600 V and supports current loads up to 19 A per contact. The assembly is supplied in bulk packaging and is currently active in production.

Headers, Male Pins Feature Summary

• Vertical through-hole design for direct printed circuit board integration
• Polyamide housing provides structural stability and thermal resistance
• Tin-plated phosphor bronze contacts ensure reliable electrical conductivity
• Locking tab mechanism secures mating connections

Headers, Male Pins Applications

• Industrial control system signal distribution
• Automotive electronic module interconnects
• Consumer appliance mainboard connections
• General-purpose low-voltage power routing

Headers, Male Pins Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm plating thickness and material composition. Ensure that the selected quantity aligns with standard bulk packaging requirements. Confirm compatibility with mating socket housings from the same MTA-156 family to maintain proper alignment and electrical integrity during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a robust, high-current vertical interconnect is required for space-constrained applications. The 3.96 mm pitch allows for wider trace spacing compared to finer pitches, reducing short-circuit risks. Consider the 19 A rating for power distribution tasks where standard signal headers may be insufficient. Validate that the operating temperature range meets the environmental demands of the final assembly.

Headers, Male Pins Part Context

This header is part of the widely adopted MTA-156 connector system, known for its versatility in general-purpose applications. The series offers various position counts and configurations, allowing engineers to scale designs without changing the fundamental interface geometry. Its standardized dimensions facilitate easy replacement and upgrade paths within existing product lines.

Headers, Male Pins Replacement Considerations

Compatible alternatives include other 16-position vertical headers with identical 3.96 mm pitch and through-hole termination. Verify that substitute parts match the housing locking style and contact plating specifications to ensure mechanical and electrical equivalence.
